Question

Given below are two statements, one is labelled as Assertion (A) and the other one labelled as Reason (R).
Assertion (A): Smart materials can be used as microsensors and microactuators, both.
Reason (R): Smart materials belong to intelligent mechanisms.
Choose the correct answer from the options given below:

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true but (R) is NOT the correct explanation of (A)
• C. (A) is true but (R) is false
• D. (A) is false but (R) is true

Hint:

Smart materials can act as sensors and actuators because of their unique properties such as shape memory or piezoelectric effects

Answer 1

The Correct Option is B

Smart materials indeed serve as both microsensors and microactuators due to their ability to change properties in response to stimuli However Reason (R) stating that smart materials belong to intelligent mechanisms is not a correct explanation for their use in microsensors and microactuators Smart materials are not necessarily part of intelligent mechanisms but they can be used to make such mechanisms
